Use InstallShield to get a registry key value script _ other

Use
Nvtype = Regdb_number;
Szkey = "\\SYSTEM\\CurrentControlSet\\Servic
Es\\{58ecc408-265e-4342-9da4-70bf1796d81d}\\parameters\\tcpip ";
SzName = "EnableDHCP"
Regdbsetdefaultroot (HKEY_LOCAL_MACHINE);
Regdbgetkeyvalueex (Szkey, SzName, Nvtype, Svvalue, nvsize);
if (Svvalue = "1") Then
SzName = "DhcpIPAddress";
Else
SzName = "IPAddress";
endif
Nvtype = regdb_string;
Regdbsetdefaultroot (HKEY_LOCAL_MACHINE);
Regdbgetkeyvalueex (Szkey, SzName, Nvtype, Svvalue, nvsize); <p> the above program is actually how to obtain the key value in the registry, if used to obtain IP, the above {58ecc408-265e-4342-9da4-70bf1796d81d} is on my machine, your GUID may not be the same as mine, But you can also get from the following registry:
Hkey_local_machine\system\currentcontrolset\services\tcpip\parameters\adapters
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
Hkey_local_machine\system\currentcontrolset\services\el90x1\parameters\tcpip (if present)


Similarly, if you want to get your hostname, you can use the following procedure:
Regdbsetdefaultroot (HKEY_LOCAL_MACHINE);
Regdbgetkeyvalueex ("System\\currentcontrolset\\control\\computername\\computername", "ComputerName", NvType, Szserverport, nvsize);

You can get other key values from the registry by using the example above.
